Telmatobius is a genus of frogs native to the Andean highlands in South America, where they are found in Ecuador, Peru, Bolivia, northwestern Argentina and northern Chile. It is the only genus in the family Telmatobiidae. Some sources recognize Batrachophrynus as a valid genus distinct from Telmatobius.
Telmatobius brachydactylus, the Amable Maria frog, is an endangered species of frog in the family Telmatobiidae.
Telmatobius macrostomus, also known as the Lake Junin (giant) frog or Andes smooth frog, is a very large and endangered species of frog in the family Telmatobiidae. This completely aquatic frog is endemic to lakes and associated waters at altitudes of 4,000–4,600 m (13,100–15,100 ft) in the Andes of Junín and Pasco in central Peru. It has been introduced to slow-moving parts of the upper Mantaro River, although it is unclear if this population still persists.
Telmatobius arequipensis is a species of frog in the family Telmatobiidae. It is endemic to southern Peru. It has an altitudinal range of 2,000–4,500 m (6,600–14,800 ft) asl. Two subspecies have been described, Telmatobius arequipensis arequipensis and Telmatobius arequipensis natatorVellard, 1955. Its common name is Chili water frog, after its type locality near Río Chili.
Telmatobius atahualpai is a species of frog in the family Telmatobiidae. It is endemic to the Cordillera Central of northern Peru and found in the San Martín and Amazonas Regions at 2,600–4,000 m (8,500–13,100 ft) asl.
Telmatobius brevipes is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are subtropical or tropical moist montane forest, subtropical or tropical high-altitude shrubland, subtropical or tropical high-altitude grassland, rivers, arable land, and canals and ditches.
The Ancash water frog is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are subtropical or tropical high-altitude grassland and rivers with stony bottoms and weak currents. This species has been assessed as Vulnerable by the IUCN under criteria B1ab(iii,v), and has an extent of occurrence of 16,946 km2 across the Central Peruvian Andes at altitudes of 3,680–4,818 m asl. All populations occur in different hydrographic systems, and could qualify as being quite fragmented in its distribution, and though not specifically recorded, anthropogenic pressures such as pollution from mining concessions, collection for food and possible chytrid infection.
Telmatobius dankoi, also known as the Loa water frog, is a species of critically endangered aquatic frog in the family Telmatobiidae. It is endemic to Chile and is only known from its type locality near Calama, in the El Loa province. Only 14 individuals are known from captivity following the destruction of its habitat prior to 2019, so it may already be extinct in the wild. However, it is doubtfully distinct from Telmatobius halli and thus may not be a distinct species.
Telmatobius degener is a species of frog in the family Telmatobiidae. It is endemic to the La Libertad Region of Peru and only known from its type locality between Otuzco and Huamachuco, at 3,290 m (10,790 ft) asl. The type locality is in the very humid subalpine páramo. The frogs were active by day and found in pools and running water in a densely vegetated roadside marsh in an open pasture.
Telmatobius fronteriensis is a species of frog in the family Telmatobiidae. It is found in Chile and possibly Bolivia. Its natural habitats are rivers, freshwater marshes, geothermal wetlands, and ponds.
Telmatobius gigas is a critically endangered species of frog in the family Telmatobiidae. It is endemic to the Huayllamarca River at an altitude of about 4,000 metres (13,000 ft) in the Carangas Province in Bolivia. Its tiny range makes it highly vulnerable to pollution, and it may also be threatened by over-harvesting for medicinal use and the disease chytridiomycosis. As suggested by its scientific name, this is a very large species of frog with a snout-vent length of up to 10.9 centimetres (4.3 in) in females. In the genus Telmatobius, only two other threatened species, the Titicaca water frog and Lake Junin frog, are larger. T. gigas is very closely related to the smaller and more widespread T. marmoratus, and they might be conspecific.
Telmatobius ignavus is a species of frog in the family Telmatobiidae. It is endemic to the Cordillera de Huancabamba in the Department of Piura, Peru. Common name Piura water frog has been coined for it.
Telmatobius jelskii, also known as the Acancocha water frog, is a near-threatened species of frog in the family Telmatobiidae, endemic to the Andes of central Peru. This semiaquatic frog is found in and near streams and ditches at altitudes of 2,700–4,500 m (8,900–14,800 ft). It breeds in streams.
Telmatobius marmoratus, the marbled water frog, is a vulnerable species of frog in the family Telmatobiidae. The most widespread species in the genus, it is found in the Andean highlands of Bolivia, northern Chile and southern Peru. It may also occur in northwestern Argentina, but the taxonomic position of this population is unclear. This semiaquatic frog is found in and near streams, rivers, waterfalls, lakes and ponds.
Telmatobius mayoloi is a species of frog in the family Telmatobiidae. It is endemic to Peru. Its natural habitats are subtropical or tropical high-altitude grassland and rivers. This species is primarily found in central Peru. They can also be found in Andes, Ecuador, Chile, and Argentina in high elevation areas ranging from 1,300 to 5,400 meters high.
Telmatobius pefauri is a species of frog in the family Telmatobiidae. It is endemic to extreme northern Chile. It was already feared that this species is extinct, but recent research has suggested that the species is extant at several localities in the Arica y Parinacota Region, albeit at low numbers. Furthermore, morphological and genetic data suggest that Telmatobius zapahuirensis is a synonym of Telmatobius pefauri. Common name Arico water frog has been coined for this species.
Telmatobius philippii is a species of frog in the family Telmatobiidae. It is endemic to Chile. Its natural habitat is rivers.
Telmatobius culeus, commonly known as the Titicaca water frog or Lake Titicaca frog, is a medium-large to very large and endangered species of frog in the family Telmatobiidae. It is entirely aquatic and found only in the Lake Titicaca basin, including rivers that flow into it and smaller connected lakes like Arapa, Lagunillas and Saracocha, in the Andean highlands of Bolivia and Peru. In reference to its excessive amounts of skin, it is sometimes jokingly referred to as the Titicaca scrotum frog.
Telmatobius ventriflavum, the Andean Water Frog, is a species of water frogs from the western Andes in Peru.
